Answer:
69
Step-by-step explanation:
as , 77+x = 146(external angle) , so x = 146 - 77
so x = 69
210 - ( 30 * x )
**I assume the question asks for total minutes.
Answer:
x < -17
Step-by-step explanation:
-3-7x - 41 - 7>68
Combine like terms
-7x-51>68
Add 51 to each side
-7x-51+51>68+51
-7x > 119
Divide each side by -7, remembering to flip the inequality
-7x/-7 < 119/-7
x < -17
Note:
sin(-θ) = -sinθ
sin(-15°) = -sin15° Use a calculator
sin(-15°) = -sin15° = -0.2588
sin(-15°) = -0.2588
The answer is b I hope this helps
